1. Floating treatment wetlands for stormwater management : Plant species selection and influence of external factors for heavy metal and chloride removal in a cold climate
Sammanfattning : Stormwater, which consists of rainwater and snowmelt, often contains pollutants from vehicle traffic, building materials, and industries. These pollutants include chloride and heavy metals, which can cause several environmental issues, such as being toxic to biota at elevated concentrations. LÄS MER
2. Samnyttjad mark och urbana allmänningar : En fallstudie av skyfallsanpassning i Malmö och Köpenhamn
Sammanfattning : I avhandlingen analyseras möjligheter och hinder för samnyttjande av mark utifrån en fallstudie av skyfallsanpassning i Malmö och Köpenhamn. Som bakgrund står de klimatutmaningar i form av ökad framtida nederbörd och risk för översvämningar som städerna ställs inför, tillsammans med en tilltagande konkurrens om marken från allt fler behov.

3. Metal pathways in stormwater treatment systems
Sammanfattning : Heavy metals in urban stormwater runoff affect the ecological status of receiving surface waters. To avoid this, various stormwater treatment systems have been developed and implemented during the last 50 years. One of themost common and continuously popular systems is wet stormwater ponds.

4. An evaluation of sources contributing to urban runoff pollution
Sammanfattning : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. LÄS MER
5. Particle concentrations : analysis methods for urban runoff
Sammanfattning : Urban runoff often contains high concentrations of particles. Pollutants that adsorbs to surfaces of particulate material will be transported to receiving waters or a sewage treatment plant. For the recipient, the particles in the runoff are a significant cause of water quality impairment. LÄS MER
